ISELF-LIGHTING GAS-BURNER.

SPECIFICATION forming part of Letters Patent No. 651,755, dated June 12, 1900. Application filed July 20, 1899. serial No. 724,568. (No model.)

To aZZ whom it may concern.-

Be it known that I, JEAN BAPTISTE GYs, manufacturer, a citizen of Belgium, residing at 67 Brogniez street, Brussels, in the Kingdom of Belgium, have invented new and useful Improvements in Self-Lighting Gas-Burners; and I do hereby declare the following to be a full, clear, and exact description of the invention.

This invention relates to self-lighting gasburners, and more especially to a cock by means of which a sure and safe operation of the burner and its automatic lighting devices will be attained.

In the accompanying drawings, Figures 1, 2, and 3 are side elevations of aburner equipped with my invention, the cock being shown in axial section. Figs. 45, 5, and 6 show the cock alone in elevation in the same position of the parts as in Figs. 1, 2, and 3. Figs. 7, 8, and 9 show the turning-plug of the cock in relatively-similar positions. Fig. 10 is an end view of the cock when the gas is shut 0E, and Fig. 11 is an axial section of the cock in this position. Fig. 12 is a cross-section of the cock through the pilot-passage when the gas is turned on. Fig. 13 is a similar section through the main passage with the plug in the same position as in Fig. 12.

The cock is composed of the casing 0t,screwed upon the upper end of the pipe I), through which the gas is supplied, and having the burner screwed upon its upper end. The turning-plug d of thecock is chambered at f and has a small channel or passage 1' leading from said chamber in line with the ignitingtube j, which rises from the shoulder Z on the casing a and terminates at a point adjacent to the burner. The plug has also a throughpassage intersecting the chamber f in line with the pipe b, the two portions of this passage beinglettered h and i. A passage q in line with the passage 72. conveys the gas up to the burner when the passages h, t, and q are in line with the pipe I).

From the outer end of the passage r runs a small groove 19, cut circumferentially in the surface of the plug (1 and tapering to a point at its farther end. A similar groove 0 is run from the end of the passage 0;, extending around the plug toward the groove 10, but in a different parallel transverse plane.

The casing has its shoulder or collar Z cut away to form abutments m m, diametrically opposite each other, and on the plugis a pin 17., which by coming in contact with these abutments limits the movement of the plug. The relative location of this pin, the passage 1", the igniting-pipe j, and the passages h i q is such that when the pin rests against the abutment m, as shown in Fig. 4, then the passage 1' is in line with the igniting-tube, and the gas is cut ofi from the burner 71;; but on giving the plug a partial turn, as shown in Fig. 5, the passage'r is carried outof line with the tube j, leaving said tube in communicae tion with the chamber f only through the groove 19 and passage r, and thus cutting off a large part of the gas supply to said tube.

All this time the groove 0 rides over the end of the main supply-pipe b and insures a sup ply of gas to the igniting-tube through the passage '5 and the chamber f.

Just before the groove 19 is entirely withdrawn from under the end of the tube j the passage It opens up into the passage q and the gas begins to flow in small quantity to the burner is, where it is ignited by the flame which still burns on the igniting-tube; but a continued turning movement of the plug shuts 0d the gas from said tube and extinguishes its flame, at the same time increasing the supply to the main burner it. When the key of the cock stands as shown in Fig. 6, the burner 76 is fully lighted. A continued turning of the plug until the pin 11. strikes the abutment m, as shown in Figs. 10 and 11, cuts 01f the gas from both the main burner and the igniting-tube as well; but if when the main burner is alight the cock be turned back to the position shown in Fig. 4 the gas is gradually out off from the burner but before it is entirely checked it begins to flow into the tube j through the passage rand the groove 19, so that the igniting-flame is lighted by the main burner just before the further movement of the cock shuts 0d the gas entirely from the burner is.

This invention is evidently applicable to all kinds of gas-burners.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

In a self-lighting gas-burner, the combina tion witha casing adapted tobe interposed I ing such that gas will be supplied to the main between'the supply-pipe and'the main burner, of an igniting-tube mounted on said casing,

and a turning plug in said casing having av central chamber, passages h and 7 intersecting the same in line with the supply-pipeand E main burner, a passageq extending from the chamber in line with the igniting-tube, a tapering groove 19 and a groove o'runnin g around i the plugtoward each other from the ends of the passages and t respectively but in plrallel transverse plane's, thearrangemen't be-J burner just before it iscu't off from the igniting-tube, and to the igniting-tube just before it is cut ofi from the main burner, substantially as set forth.

In testimony that I claim the foregoing I h ave hereto set my hand'this 8th day of July,

, JEAN BAPTISTE GYS.
